Uniqlo long-sleeved knit sweater. It's a solid color, so it's easy to coordinate. I think you can wear it from fall to early spring＾＾ Also, it's labeled as size S, but it has a relaxed design. There are no noticeable stains, but there are small pills and a feeling of wear. Instant purchase is OK, but if you have any questions, please comment before purchasing.
